Mirai Variant V3G4 Targets IoT Devices

Unit 42 tracked the Mirai variant V3G4 exploiting 13 vulnerabilities across IoT devices and servers from July-December 2022 to build a DDoS botnet.

From July to December 2022, Unit 42 observed three campaigns spreading V3G4, a Mirai botnet variant, by exploiting 13 vulnerabilities, including CVE-2022-26134 in Atlassian Confluence and CVE-2019-15107 in Webmin. The campaigns shared the same C2 domains containing the string 8xl9, nearly identical shell script downloaders, and the same XOR keys, suggesting a single threat actor. The malware brute-forces telnet and SSH credentials, terminates rival botnet processes via a stop list, and receives DDoS commands from its C2. Compromised servers and networking devices are absorbed into the botnet for further attacks.

FBI Disrupts China-Linked QTFY Infrastructure Used to Steal Data From U.S. Organizations

FBI and Lumen disrupted QTFY's QScan and QTRouter botnet platforms used by Chinese state-sponsored hackers to conceal intrusions into U.S. agencies.

The U.S. DoJ announced court-authorized seizure of domains behind QScan and QTRouter, operated by the Chinese state-sponsored group QTFY and employed by Nanjing Xinjiuwei Network Technology Company. QTFY has been active since May 2018 and targeted NASA, the Federal Reserve, the Department of Energy, DoJ, HHS, NIH, the U.S. Senate, and academic institutions. QScan exploits vulnerable IoT devices, feeding them into QTRouter, an OpenWrt-based proxy obfuscation network likened to an operational relay box (ORB) that masks attack origins. The group exploited zero-days such as Ivanti CSA flaws CVE-2024-8190, CVE-2024-8963, and CVE-2024-9380, plus numerous N-days, and maintained persistence with RATs, web shells, and legitimate credentials.

Evooo1Bot Linux Botnet Exploits Known Flaws to Turn Edge Devices Into SOCKS5 Proxies

Fortinet researchers documented Evooo1Bot, a new Mirai-derived Linux botnet active since July 2026 that exploits known edge-device flaws to build SOCKS5 proxy networks.

Fortinet FortiGuard Labs identified Evooo1Bot, a previously undocumented Linux botnet built on the leaked Mirai source code, active in the wild since July 2026 and targeting internet-facing edge devices. It exploits numerous known CVEs in routers and devices from D-Link, Tenda, Telesquare, Zyxel, Hikvision, Atlassian Confluence, WSO2, TP-Link, NETGEAR, and others, delivering a bot binary via a wget.sh loader from 91.92.40.118 that clears bash history. The bot offers encrypted C2 on port 443, SSH brute-force scanning, credential sniffing, DDoS over DNS/TCP/UDP, an HTTP exploit dispatcher, and converts infected hosts into SOCKS5 proxies for anonymizing follow-on operations.

Risky Bulletin: Academics find source code overlaps between Geedge and China's Great Firewall

Academics linked Chinese vendor Geedge Networks' Tiangou Secure Gateway source code to one of the Great Firewall's three traffic filtering capabilities.

US researchers presenting at USENIX Security reconstructed Geedge Networks' Tiangou Secure Gateway firmware from over 100,000 leaked files, including Git repositories with commit history, and matched its filtering behavior to sections of China's Great Firewall. They found only 1 of 3 characterized DNS injectors matched Geedge code, noted the system relies on memory-unsafe C components and copied third-party code, and said its bugs could aid future circumvention tools. Geedge also exports censorship tools to Kazakhstan, Ethiopia, Pakistan, and Myanmar. The newsletter additionally rounds up multiple breaches.

VU#943094: ONLYOFFICE ownCloud integration plugin contains a Server-Side Request Forgery (SSRF) vulnerability

ONLYOFFICE's ownCloud integration plugin 9.12 has an SSRF flaw (CVE-2026-84282) letting authenticated admins probe internal networks; no patch exists yet.

CERT/CC published VU#943094 for a server-side request forgery in Ascensio System SIA's ONLYOFFICE ownCloud integration plugin version 9.12, tracked as CVE-2026-84282. The /apps/onlyoffice/ajax/settings/address endpoint does not validate the user-supplied document server URL, so an authenticated administrator can make the ownCloud server send arbitrary requests to localhost and internal hosts. Differences in error responses (connection failures vs SSL/TLS errors) let attackers enumerate open and closed TCP ports for internal reconnaissance. The vendor could not be reached, so no official patch is available; CERT recommends disabling the plugin and applying egress filtering until a fix ships.

CVE-2026-82428: Apache Storm Client: Cross-Tenant Dependency Jar Substitution via Predictable Blob Keys

Apache Storm stores shared dependency jars under predictable Maven-derived blob keys, allowing one tenant to substitute jars other tenants execute.

CVE-2026-82428 affects Apache Storm Client (org.apache.storm:storm-client) versions 3.0.0 before 3.1.0, rated important. Dependency artifacts uploaded with storm jar --artifacts were stored under blob keys derived only from the Maven coordinate, making keys identical and predictable for every cluster user. When a blob already existed, the uploader suppressed the collision, enabling a tenant to substitute dependency jars later executed by other tenants in cross-tenant attacks. Fixed in version 3.1.0.
